I have used a wiki to share student videos with parents. First they draw and write about their favorite book and we turn these into a Quicktime movie to embed in the wiki. Here is the page from last year:

Later in the year, my students create an video book using Keynote. They record themselves reading the book they have written. Then we export the Keynote as a Quicktime video and embed it into the wiki. This way parents can see it. To see an example, visit:

I checked out the wiki with the studen videos and that is really neat! i am sure the parents enjoyed seeing those! You came up with a really great list of pros and cons for the two sites! -Allison Herrlein

Great movies on you wiki! Looks like your students had fun creating those. I've used wikis as well to showcase student work. I didn't even think about how sutdents cold delete each other work on a wiki. That is a pretty big concern in my books. -Tyler Muth
I really like how you sorted everything into a table- very easy to read and understand! I also like how you pointed out that wikispaces does not save automatically and students could delete each other's work- could be very problematic for those that are unfamiliar with technology, or are causing trouble. I like how you used a wikispace for sharing videos- looks very cool!- Kara Wevik
